View showing the locking mechanism. My hoisting-bucket receptacle is provided near the upper rim thereof with two ormore reinforced holes or openings 1), in which adjustable grip or lever tongs engage for the purpose of raising the same from or lowering the same into the barge, vessel, or vehicle being unloaded or loaded.

My invention is adapted for use in conjunction with a crane or derrick of any known construction and will perform all the functions of loading or unloading boats, cars, or.

other vessels or conveyances with a great saving of time and labor. my bucket-receptacle may be filled from the chute and that all shoveling may be dispensed with either in the filling or emptying of the same. It is also obvious that my hoistingbucket receptacles may be made in various sizes and of many materials, which is a matter to be regulated by the nature and quantity of the material desired to be carried in them, and without departing from the essential principles of the invention.

The locking mechanism may be manipulated for the purpose of looking or unlocking the bottom either by means of a hand-key or wrench by hand directly, or indirectly by means of a rope or wire,which may be connected with said key or wrench and. which may be operated from a distance.

With this description of my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A bucket having four walls, and an automaticallyclosing spring -actuated bottom having upturned sides forming a chute through which the contents of a bucket may It is obvious that be delivered, and alockingmech anism to keep said bottom closed when desired, constructed substantially as set forth.

2. In aloadingorunloading device,a bucket having four walls, an automatically-closing spring-actuated bottom, and a locking mechanism to keep said bottom closed, the walls being provided with openings to be gripped by the hooks of a hoisting apparatus, said bucket being adapted to be raised from or lowered into a vessel, substantially as set forth.

3. A bucket having four walls, a hinged bottom having upturned sides forming a chute to deliver and guide in the discharging of the contents of said bucket, means for automatically closing said bottom when the bucket is empty, and means for looking and unlocking said bottom when closed, said bucket so constructed that it may be gripped by a hoisting apparatus.

4. In combination with a hoisting-bucket, a locking mechanism consisting of int-ermeshing gears, bolts pivoially connected with said gears, and adapted to be shot into operative relation with the bottom, a square-headed stud on one of said gears projecting through wall of bucket, and a sloping cover or casingcovering, and protecting said locking mechanism in the interior of the bucket, substantially as set forth.

In testimony whereof I aifix my signature in presence of two witnesses.

THOMAS J. PRATT.
